Dr. Charles S. Zwerling

I specialize in the medical and surgical management of cataracts and glaucoma. I believe in partnering with my patients to create an optimal, evidence-based treatment plan for each individual. Because glaucoma requires lifelong care, I feel privileged to be a part of the lives of my patients and particularly enjoy getting to know patients and their families as we work together to treat their eye conditions. I have a number of research interests that focus on developing new technologies to diagnose glaucoma as well as developing new ways to measure eye pressure. When not working, I enjoy traveling and spending time with my family, gardening, and cooking. Dr. Wen is rated as a Distinguished provider by MediFind in the treatment of Glaucoma.

I am a native North Carolinian, having grown up in Raleigh, NC. I went to UNC-Chapel Hill for my undergraduate degree in Biology and attended Medical School there as well. I remained at UNC to complete my residency in Ophthalmology. I then came to the school with a deeper shade of blue to complete my fellowship year in Glaucoma and joined the faculty at the Duke Eye Center in July of 1996. I knew I wanted to be an eye doctor in 9th grade when I received my first pair of glasses. I could see clearly now, and I decided to dedicate my life to helping others improve and/or maintain their vision. My approach with patients is to put them at ease, as often they are concerned about going blind. I give them an opportunity to share with me their concerns, then I make recommendations based on the best available literature and my personal experience.

His top areas of expertise are Glaucoma, Ocular Hypertension (OHT), Cataract, Trabeculectomy, and Cataract Removal.

I treat patients with glaucoma and cataract with evidence based medical treatments, lasers and surgery. Using the latest imaging techniques, I am able to detect glaucoma and its progression at the earliest stages. My research interests include technologies that may help to prevent the onset and progression of glaucoma. I am involved in clinical trials for emerging treatments for glaucoma. When not working I enjoy traveling with my family, and spending time with our dog. I also enjoy listening to Indian classical music.
